Once again, a repetition - Yes, you can get Dengue Fever again. A person who was previously infected with dengue will only gain immunity for the particular virus serotype. There are a total of 4 serotypes of the dengue virus. What happens when you get Dengue Fever:
Dengue fever is characterized by the sudden onset of fever, (which can last up to 7 days) and is accompanied by intense headache, body aches, joint pains, loss of appetite, nausea, vomiting and the development of skin rashes. A blood test will often show low platelets.
When you get dengue fever, your blood platelet count drops. This means your blood is effectively unable to clot. If you cut yourself or hurt yourself in any way, you will literally bleed to death. That's one danger of dengue fever. I guess, for the layperson, one of the first signs is seeing a lot more blood when you brush your teeth. (Please refer to the website below for more symptons)
Dengue haemorrhagic fever is a more severe form of dengue and can be fatal if unrecognised or not treated.
Dengue haemorrhagic fever presents similarly to dengue fever but is associated with more severe bleeding problems (e.g. gum bleeding, nose bleeding and bleeding into the skin and internal organs) along with evidence of plasma leakage. Hospitalisation:
When you are hospitalised, this is what happens:
1) They try bring down your fever. This will include giving cold baths, etc. as excessively-high fevers can destroy important cells in the body.
2) Boost your immunity, e.g. vitamin C supplements
3) Boost your platelet count
If you have DF, you are hospitalised so that they can measure your platelet count, and just in case, you bleed (so that you can receive immediate medical attention). Otherwise, they pretty much leave you alone.About your Dad:
If he is dialect-speaking, you can refer him to the Ministry of Health website. There are "Dengue Patient Advisories" in English, Mandarin, Malay and Tamil.
If he does not want to be hospitalised again, do this:
- Drink lots of water
- Visit the doctor every day for a platelet count check
- Avoid medication containing aspirin / pain-killers (as they increase chances of bleeding)
- Avoid anti-inflammatory drugs as they may cause gastric bleeding

Do be more cautious if you happen to stay in a dengue hotspot (http://www.moh.gov.sg/dengue_hotspots).
Hope this helps...
